The primary method for assessing ecosystem services is through valuation techniques that quantify the benefits humans derive from ecosystems. Common approaches include economic valuation, where services are assigned monetary values, and non-monetary assessments that capture social and ecological values. Methods like contingent valuation, market pricing, and basket of goods analysis are frequently employed. Understanding these services aids in policymaking and environmental management, as it highlights the importance of preserving ecosystems in terms of their contributions to human well-being and sustainability.
